An entry is usable only when its executable is supported on the current platform and available to the Kandev process.

Hermes launches with `hermes acp`. Install the required `hermes` executable from its **Settings > Agents** card, which runs the official Hermes installer. Hermes currently supports task and workspace sessions. Office-assigned skill injection is not yet supported.
Antigravity has no automated install: Google distributes `agy_acp_server.par` (`agy_acp_server.exe` on Windows) and its `localharness_external` or `localharness` sibling (`localharness_external.exe` or `localharness.exe` on Windows) as a signed archive through the [ACP registry](https://github.com/agentclientprotocol/registry/tree/main/antigravity-acp) rather than npm, so extract both files into one directory and add it to PATH yourself. Kandev fails discovery closed when the harness sibling is missing or not executable, so a partial extraction reports as not installed rather than as a broken session.
### Pi command surfaces
Pi uses separate executables for its two Kandev modes:
